IMPROVEMENT IN OIL-CUP FOR MACHINERY.-

TO ALL WHOM IT MAY CO'NCERN:

Be it known that we, WILLIAM DoUGLAs and Hman M. INsLuu, of Bellnir, in the county of Belmont, and State of Ohio, havev invented a new and useful Improvement in Oil-Cups; and we do hereby declare that the` following is a full, clear,land exact description thereof, which will enable those skilled in the art to make and .use the same, reference being had to the accompanying drawings, forming partot` this speeiiication.

Our invention consists inso constructing an oil-eupthat the oil that reaches the wrist-pin or journal, shall be discharged upward by the motion ot' the cup on the crank through a hole so small that the quantity discharged shall only be suiiicient to lubricatc the wrist for which itu-is intended. In the accompanying drawings- Figure 1 represents a vertical section of oni-.oil-cup.

vFigure-2 is a top View of the oil-feeder.

Similar letters of reference indicate corresponding parts. p

A is the cup containing the oil; B is the screw or neck by which it is'attaeh'ed to the crank C is thc'cap of the oil-cup; D is the conical oil-feeder; E is the stopper in the centre ofthe cap; a a are apertures through the shell or sides of the cup to convey the oil from the feeder and from the cap to the wrist-pin. The `cup is formed, as represented in the drawing, with a neck, B, by which it is attached to the crank of the engine. The space A contains the oil.l The holes a a communicate with the wrist-pin through the hole d in the neck.. The feeder D is a loose conical piece laid on the top ofthe cup A. The upper side of it is conical, as seen in the drawing. At the base of the cone there is a channel, e, and near the outer edge there are holes y to convey the oil from the feeder tothe Maoertures aja. The channele and the holes t communicate with each other the u er l J a PP part of the holes being slotted tothe channel. There are holes y through the feeder for two guide-pins which vare'in the cap (I. These pins enter the holes and keep the feeder in such a position that the oil-holes through it and the holes c a in the cup correspond. Through the apex of the cone there is a small hole, through which the oil is thrownin small quantities when the crank is in motion. The oil thus thrown through the small hole runs down the sides of the conc into the channel e, and through the holes g and a a and el to the wrist-pin. By this arrangement theA small hole in thc cone-feeder is always kept open and clear by the foree'oi' the oil inthe cup while the engine is n motion, as the oil is violently thrown upward at every revolution, while any sediment or foreign substances would be likely to remain near the bottom o f the cup. By means of the hole through the cap C we arc able to lubricate the pin directly in case of necessity, as oil pouredinto this hole reaches the wristpin immediately. The cap is screwed on to the cup as seen in the drawing, and the cone-feeder D is confined between the two.

Having thus described our invention, what we claim as new, and desire to secure by Letters Patent, isl The conc-feeder D, constructed and arranged substantially as described, for the discharge oi' the oil upward by the motion of the engine-crank.

We claim the arrangement, substantially as herein described, for oiling the wrist-pin directly in combination with an upward-feeding oil-cup.
